#3836: Parallel support for ST_CountAgg, ST_SummaryStatsAgg
---------------------+---------------------------
 Reporter:  pramsey  |      Owner:  pramsey
     Type:  defect   |     Status:  assigned
 Priority:  medium   |  Milestone:  PostGIS 2.5.0
Component:  postgis  |    Version:  trunk
 Keywords:           |
---------------------+---------------------------
 Continuing from #3751.

 * ST_CountAgg
 * ST_SummaryStatsAgg

 These two aggregates are candidates for parallel aggregation. They are
 already marked parallel safe in their current incarnation.

 They require a combinefunc, and serialize/deserialize functions.
 Unfortunately each has several different SQL function parameterizations,
 so it'll be a little complex to carry out.
